Witty is very responsive and helpful. He gave the address in Thai- which is so useful with cab drivers. We also arrived after midnight and checking in was no problem. We also met with him the next morning for breakfast and he gave us some really great recommendations based on our expressed interests. The apartment is a local part of Bangkok about 2 MRT stops outside of central Bangkok. The MRT is super easy and fast to use. There are also numerous food stalls and 7 elevens near by as well as a grocery store about 15 mins walk away. The apt itself is bright and clean, basic but a good base. There is also a basic gym you can use for 30 baht each use and a washing machine on the balcony.
